I wanted to know what disadvantages ESRI plug-in data sources have when compared to custom layers. I am looking to implement a fairly large (in terms of average dataset size) read-only custom type for ArcMap and ArcScene.
I have read the chart here. I was wondering if there are any other disadvantages or major issues with plug-in data sources.
In particular, has anybody experienced issues related to performance, integration and interoperability with the Desktop tools, or any other significant issues?
